IMPROVEMENT IN IILTRING BURNING-FLUID.

To ALL WHOM IT MAY coNoERN:

Be it known -that I, JOHN D. KIRKPATRICK, of Urbana, in the county of Champaign, and State of Ohio, have invented a new and useful Improvement in Filtering Burning-Fluids; and I do hereby declare the following to be a full and correct description of the same, suliczient to enable others skilled in the art to which my invention appertains tov'fully understand and use the same, reference being had to the accompanying drawings, which make part of this invention, and in Which- Figure l is a front perspective view of the apparatus for ltering.

Figures 2, 3, and 4 are detached vieivs of the same; and l Figure 5, sheet 2, is a vertical cross-section of the apparatus, showing the process of filtration.

Like letters idicate like parts in the several figures.

My invention consists in the consecutive filtration of burning-liuidsthrough diierent'ingredients in a peculiar apparatus, by means of which said fluids lose their o'ensive odor and explosive qualities.

My process dii'ers materially from vthe many Ways that have been tried to accomplish this object in passing the iuids through the ltering-agents, instead of mixing the latter with'the iuids, the advantages of which will be hereinafter fully'set forth., i

In the drawings, A. may represent a base, from which rise the four walls of a compartment, B, which is providedwith avdoor, C, forming a part of the front sideLB. The top of theapparatus is closed by a lid, Four sets of angesfe, on opposite inner sides of the apparatus, support tubs or vessels a l c d, provided with perforated bottoms a b c d. These vessels may, when the door C is opened, either slip out of or into the apparatus on the flanges eY The' bottom of the apparatus forms a reservoir, G, to receive the deodorized 'and lclarified uid, from which it can be drawn forsale or use in any desired quantities throughthe cock E.

Fig. 2 is a topview, and iig. 3 a side elevation' of my improved filtering-vessel.

F is a false bottom, which, if desired, may be applied to every one of the vessels a b c d. It fits closely over the perforated bottoms of the, same, and its handle,f, is pivoted to the rimof the vessel, and protrudesv through the side of thelapparatus, so as to be operated from the outsideof the latter. Aloop or band,.g,.

holds it in an open position'. By this false bottom F `the iiow of the uid'may be shut off from any one or more of the vessels. In fig. 4 this bottom, F, is shown open in black lines, and closed in red-ones.

Fig. 5 illustrates my process. The lid D, Vbeing opened, the'uid is poured into the vessel a. This sessel is covered on its inside with a piece of annel, upon-which the first ingredients, pulverized lime and woodashes, are strewed in. such quantities as may be necessary. The luid'sickers through the bottom, a', of the vessel into the vessel b, which is covered with flannel, like` the vessel a, but contains elm-bark, partly pulverized and'partly in short pieces. In ltering through the same, the fluid falls into vessel a, covered likewise with-annel, and filled with nely-pulverized charcoal. Passing through this, the duid finally reaches vessel bl, which, on a dannel covering, (similar to the other vessels, l contains fine sand. From this vessel the :duid drips into the reservoir G, purified and deodorized, and can be drawn from the same for use or sale. vThe lime and wood-ashes deodorize the fluid by absorbing the strong and o'ensive odor common 'to all unclarified burning- Huid. Thus deodorized, the Huid passes through the layer of elm-bark. At this stage of the process the duid absorbs a great many of the mucilaginousparticles of thelelni-bark, which not only imparts a body to the duid, but also imparts to it the sweet odor of the bark. Its evaporation isv stopped, and it is thus rendered, in connection with the other filtering-ingredients, non-explosive. The charcoal and sand in Vthe other vessels, c d, have a purifying eifect uponvthe fluid, and nish the process. The great advantage I gain by filtering the-duide through the ingredients separately, instead of mixing -the ingredients with the Huid inthe barrel, is this, that I can allow the fluid to remain in any one of thel .ingredients for any leng'th of time, by closing the' false bottom F, if it should be desirable, and that by my process I obtainan absolutely puriiied, clarified, and non-explosive article, all impurities not only being destroyed, but absorbed .by thehingr'edients, as theiuid passes through the same during the filtering process.

I do not confine myself to the precise shape of the apparatus, vessels, and reservoir, as they may bemade round or polygonal, and of di'erentcapacities. The appagatus may be constructed in such shape or size that poses described.

each groom-*may purify his own liuids in thestore, amd sell the latter from the reservoir. The order of the ingredients, however, is essential. v

What I claim as new, and desire to secure by Letters Patent, is-

1. Filtering burning-fluids consecutively through separate laye'rsof lime and wQo-ashes, elm-bark, chir-4 coal, and sand, each-ingredient being placed on flannel, in the bottom'of the filtering-vessels,substantially a and for the purposes set forth.

2. The filtering-apparats, oqnssting of the bottom, A, frame B, vessels a b e d, with perforated bottoms a 1;"c d', and false bottom F, and reservoir G, pfovided with stop-'cock E, 4substantially as and for the .pur-
